T above nd er o ts a arent rom th d a ings a d ll n r on. ma be a ainethe a ove described difiiculties overcome and the advantages and resultsobtained, by the apparatus, construction, arrangement and combinations,subcombinations and parts which comprise the present invention, apreferred embodiment of which, illustrative of the best mode in whichapplicant has contemplated applying the principle, being set forth indetail in the following description and illustrated in the accompanyingdrawings.

In general terms, the invention may be stated as comprising a permanentshutter, sheet metal awning, including a frame formed of a pair ofchannel section rafters with means for attaching the upper ends thereofto a wall above a window or door opening, and inclined downwardly andoutwardly from the wall, an angular front bar attached to the lower endsof the rafters and substantially horizontal twisted ornamental side armsattached to the front bar and to the wall as by attaching clips fixed tothe outer ends of the side arms and notched to engage the front bar.

Each of the rafters has a series of equally spaced key hole typeopenings therein, and a series of clips, having notched lower endportions, are inserted into these key hole openings and permanentlyattached to the rafters, transversely disposed sheet metal louvers beingattached to the clips, each louver having a depending flange at itsfront edge and an upstanding flange at its rear edge for engagementunder a struck-out tongue upon the adjacent clip, whereby the louversand clips are rigidly held together as a unit upon the rafters, and asheet metal valance attached to the lower ends of the rafters and havingan upturned flange at its upper end engaging the struck-out tongue ofthe lowermost clip.

The improved non-adjustable shutter awning thus set forth in generalterms is illustrated in the accompanying drawings, in which:

Reference is now made to the embodiment of the in- Vention illustratedin the drawings, in which similar numerals refer to similar partsthroughout.

The awning includes a frame, comprising a pair of downwardly andoutwardly inclined, inverted channel section rafters indicated generallyat 10, an angular front bar indicated generally at 11, and a pair ofsubstantially horizontal twisted ornamental side arms 12.

The depending flanges 13 of the rafters 10 are slit at a point spacedfrom the upper end thereof, as indicated at 14, and the web portion 15of the rafter is s ngularly bent at this point, as shown at 16', theadjacent end portions of fl g 1. be ng verlap e ind ca d a 17, andperforated to receive a cotter pin or the like 18 3 which holds therafter in a bent position, as best shown A transversely disposed stud 19is located within the upper end of each rafter 10, being attached at itsends to the flanges 13 of the rafter in any usual and well known manner,as best shown in Figs. land 4, for detachably connecting the rafters toa wall 24 above a window opening 25, by any suitable attaching means,such as the screw eye or hook 2% which may be specially designed forthis purpose.

The web portion of each rafter is provided, at equally spaced pointsthroughout its length, with substantially key-hole shaped slots,indicated generally at 28, these slots being best shown in Fig. 6. Eachslot 28 has the central, restricted portion 29 and is enlarged at oneend by the lateral cut-out portions 30, and enlarged to a less degree atthe other end'by the lateral cut-out portions 31. V

The front bar 11 is of angle cross section and is located horizontallyand connected to the lower ends of the rafters 10, which, as shown inthe drawings, are inclined downwardly and outwardly from the supportingwall.

The relatively narrow flange 32 of the front bar is of considerably lesswidth than the depth of the channel shape rafters, and is butted againstthe terminal ends of the web 15 and flanges 13 of the rafters, as bestshown in Fig. 5, the relatively wide flange 33 of said front barcontacting the lower or inner edges of the flanges 13 of the channelrafters. V

The front bar 11 is rigidly attached to the lower ends of the rafters10, as by the bolts 34 and nuts 35, which also attach the valance 36 tothe awning frame. The valance is formed of sheet metal having theupwardly and rearwardly bent portion 37 lying flat upon the top of therafters and terminating at its upper end in the upturned terminal flange38, for a purpose to be later described. The depending lower portion 39of the valance may be provided with the scalloped edge 40 as best shownin Figs. 2 and 3.

The side arms 12 may be twisted ornamental metal bars, to the forward orouter ends of which are attached the clips 41 which are angularlynotched at 41a to receive the relatively wide flange 33 and engage overthe edges of the relatively narrow flange 32 of the front bar, thuslocking the side arms 12 to the front bar 11, as shown in Fig. 1.

The rear or inner end of each side arm 12 terminates in an angularflange 42, having a bayonet slot 43 therein, whereby the same may bedetachably connected to a screw or other stud 44 secured to thesupporting wall 24-. With this construction the entire awning as a unitmay be easily and readily attached to or detached from the supportingwall without requiring the use of a screw driver, wrench or other tool.W

A single sheet metal louver 45 is permanently attached to the bent upperportions of the rafters 10, as bybolts 46 and nuts 47 located throughsuitable perforations 4S and 49 in the louver 45 and Web portions 15 ofthe channel rafters.

An upwardly and inwardly inclined terminal flange 50 is formed at theupper or rear edge of the louver 45, the terminal edge thereofcontacting the supporting wall 24, as best shown in Fig. 4. The forwardor outer edge portion of the uppermost louver 45 extends forwardly,beyond the bends 16 in the rafters, as indicated at 51, and terminatesin the down-turned angular flange 52.

All of the other louvers, which are connected tothe downwardly andoutwardly inclined portions of the rafters and extend from the bends 16in the rafters to the lower ends thereof, are preferably substantiallynarrower than the uppermost louver 45, and each of these louvers,indicated generally at 53, is'provided with an upturned, angular flange54 at its upper edge and a down-turned, angular flange 55 at its loweredge.

The louvers 53 are attached to the rafters 10 by means of clips,indicated generally at 56 and shown in detail in Fig. 8. These clips arepreferably formed of heavier guage metal than the louvers, and each clipcomprises generally the upright portion 57 and the forwardly disposedflange 58 at its upper end.

Stepped notches are formed in opposite edges of the upright portion 57of each clip, near its lower end, each notch comprising the relativelydeep upper portion 59 and the outwardly stepped lower portion 60.

To attach the louvers 53 to the rafters 10, the clips 56 are insertedinto the. key-hole slots 28 in the web portions of the rafters, thelower end of each clip being first inserted through'the widest portion30-30 of the corresponding slot 28, to a suflicient depth so that theclip may be moved upwardly and rearwardly in the slot, the narrowestnotched portion 59-59 -of the clip passing through the; narrower portion29 of the slot, the clip being moved upwardly and rearwardly into thecut-out portion 31-31 at the rear end of the slot 28, and then pulledupward, so that the stepped notches 60-60 in the clip contact thecut-out portions 31-31 of the notch.

The upper or rear terminal flange 54 of the louver 53 is then insertedunder the struck-out tongue 61 of the clip 56, this flange 54' of thelouver thus holding the clip in this position. The lower or forward endportion of the louver 53 is then riveted or otherwise permanentlyattached to the top flange 5 8 of the next lower clip and this action isrepeated as each louver and clip is assembled.

The upturned flange 54 at the upper end of the uppermost louver 53 isreceived under the down-turned flange 52 of the top louver 45. Theupturned flange 38 at the upper edge of the valance 36 is received underthe struck-out tongue 61 of the lowermost clip 56.

From the above it will be obvious that a simple, economical and durablesheet metal awning, of the permanent or non-adjustable shutter type isprovided, in which the frame members may be easily and readilyassembled, and the louvers may be quickly and easily attached to theframe, and permanently held in position thereon by means of novel clips.

It will also be seen that the entire assembly of awning and frame may beeasily and readily attached to a supporting wall, over a window or dooropening, or detached therefrom, without requiring the use of tools.

In the foregoing description, certain terms have been used for brevity,clearness and understanding, but no unnecessary limitations are to beimplied therefrom beyond the requirements of the prior art, because suchwords are used for descriptive purposes herein and are intended to bebroadly construed.

Moreover, the embodiments of the improved construction illustrated anddescribed .herein are byway of example, and the scope of the presentinvention is not limited to the exact details of construction.

Having now described the invention or discovery, the construction, theoperation, and use of preferred embodiments thereof, and theadvantageous new and useful results obtained thereby; the new and usefulconstruction, and reasonable mechanical equivalents thereof obvious tothose skilled in the art, are set forth in the appended claims.
